4 Claims. (01. 220-63) This invention relates to metal barrels and hasespecial reference to a sheet steel barrel havingv a stainless steelliner and is a division of my application, Serial No. 611,977, filedAugust 22, 1945 for a Liner and Tap Ring for Steel Barrels which hasmatured into Patent No. 2,460,756.

It is one of the principal objects of this invention to simplify theconstruction of steel barrels, such as contemplated herein, and toimprove the efficiency and dependability of such barrels.

A further principal object is to construct a steel barrel with astainless steel liner in a manner which effects a much. stu-rdierassembly than stainless steel barrels heretofore produced. In thisconnection the barrel shell is comprised of a plurality of sectionsunited by welding; the arrangement being such that the relatively thinliner is not noticeably affected by the welding operation which joinsthe shell sections.

Still another object resides in providing a liner of stainless steel fora sheet steel barrel wherein the interior of the barrel presents anapproximately continuoussmooth inner surface which is unbroken byoutwardly bulged pockets, which form deep recesses or-the like whichrender the cleansin of the barrel a difficult and uncertain operation.As a result this assembly produces a barrel of a highly sanitarycharacter.

' Also it is an'object hereo'f'to provide a lined sheet steel barrelwherein the liner conforms to the inner contour of the shellsubstantially throughout the superficial area of the interior surface ofthe shell, whereby the liner has a continuous unbroken surface and iseffectively supported by the shell without extraneous devices.

Still another object is to provide a chime arrangement for a stainlesssteel lined metal barrel wherein the chime rings are made separate fromthe barrel shell, thereby eliminating the necessity of forming thechimes integrally with the shell. Prior barrels on which the chimes aremouths of the pockets.

Another object is to provide a stainless steel lined metal barrel, theshell of which comprises two or more suitably shaped sections, with theapproximate margins telescoped and united by a welded seam. Thisarrangement allows slight endwise variations for assembling the shellsections in encompassing relation to the liner to se- 2 cure a surfacecontact fit of the liner in the shell. Also there is a slight clearancebetween the joint or" the shell sections and the liner to prevent heattransfer during welding the joint.

The above mentioned and other aims or advantages of the presentinvention will be apparent to persons skilled in the art aftertheimprovements contemplated herein are understood from the withindescription taken in connection with the accompanying drawing whichforms a part hereof, in which:

Fig. 1 shows the improved barrel in elevation with portions thereof inbroken away section.

Fig. 2 is an enlarged fragmental section showingdetails of the tap holefitting assembled with the barrel head and liner.

The drawings are to be understood as being more or less of a schematiccharacter of the purpose of disclosin a typical or preferred form of theimproved metal barrel assembly contemplated herein.

The. body or shell of this barrel is of an all metal type ofprefabricated sheet steel construction and comprises two similarlyshaped sections I0 and II. These shell sections are of relatively deepbowl-shape, the rims or margins of which have radially offset portions0a and Ha, respectively, extending circumferentially around therespective sections. The-shape and dimensions of offset portions Illaand Ila are such that the rim of one section may be telescoped on therim of the other section and then welded togetherv .to assemble thecomplete barrel shell.

This arrangement permits of slight variations when assemblingthe shellsections l0 and II over the liner with which the barrel may be provided,as

will later appear.

The heads 12 of the barrel are of shallow dome shape and atthe junctionswhere'the domes meet the side walls of the shell there are terminalregions I3 having a segmental or arcuate cross section. Adjacent theseterminal regions l3, the barrel shells have abutments I4 which are madeby providing well-defined shoulders in the walls of the shells. Thepurpose of this corner or terminal arrangement is to provide an improvedand dependable manner of quickly assembling the chimes on the barrel.

The usual bung-hole fitting I5 is inserted in an aperture locatedcentrally in the barrel, said fitting belng anchored to the margin ofthe bunghole in any suitable manner, preferably by a leak-proof weldedseam. Sheet metal bilge hoops 18 having u section with lateral wings i1embracing the mid-region of the shell, are welded on the exteriorthereof to constitute the rolling tracks or rings of the barrel.

The chimes 18 at the ends of the barrel are made of separate blanks orstrips of steel which are anchored to the barrel in a novel andeffective manner which avoids theformation of pockets in the shell andthe use of reinforcement incident thereto in either a lined or unlinedbarrel. The construction and arrangement of these chimes are such thatthey effectively reinforce and support the ends of the barrel, and theyprovide hand-grips by which the barrel may be lifted. Each chime l8comprises an annulus of L'-shaped cross section having a radiallyinwardly extending flange l9, and an axially extending attaching flange2a which is, in effect, a c ntinuation of the barrel contour. Flanges i9and are reinforni 'ed by a plurality of channels or indentations 19a and23a, respectively, and the inner margin of radial flange is has a rolledbead 2! as shown in Fig. 1. Chime flange 28 also has a segmentally orarcuately formed region or annular outwardly curved emboss'ment 22extending alongits margin, the inner surface of which fits the curvedcorner or terminal region is of the barrel to which it is united bywelding. As seen, the margin of embossment 22 abuts shoulder M on theshell, and when the chimes are assembled on the shell they arepreferably anchored tothe shell by a welding operation which may beperformed at the same time the hoop I6 is welded in position so thatboth operations are performed on one machine, thus reducing time andlabor.

The tap fitting 23 is preferably made from stainless steel and is shownas comprising the axial tubular stub 24 terminating at its inner endwith an annular flange 25 on which there is a shoulder 28. The centralregion of the barrel head has an inturned axially extending cylindricalportion 21 terminating in a lateral flange 28 arranged radially to theshoulder 2-6 of the fitting 23 and to which it is anchored by an outsideweld in the manner hereinafter described. Conceivably, other types offittings, allowing for different closures, could be attached in asimilar with their proximate edges abutting and welded together at 3!.The cuter contour of the assembled liner conforms in practically allrespects to the inside contour of the barrel shell or body, and

.its inner surface has a smooth contour which facilitates the cleansingof the barrel and insures a sanitary condition. At th'e offset portionsIlla.

and i la of the barrel shell the liner has a slight clearance 32 betweenit and the shell which provides a gap to prevent heat transfer from theshell to the liner when the shell sections are being welded. Otherwisethe liner isin intimate contact with allportions of the barrel shell sothat it is effectively'supported by surface contact therewith. V

Adjacent the'tapfitting'fl the head of the liner curves inwardlyas'at'33 providing a depressed central region with oblique walls. Thisdepressed or oblique region 33 of the liner terminates inwardly in an.L-shape flange 34 having a cylindrical shape and axially disposed withrespect to the tap fitting 23. In assembling the liner flange 34 withthe fitting, the flange 25 of the fitting is pushed into the cylindricalportion 34 in a telescopic manner so that the lateral or radial lip ofliner flange 34 is interposed between the shoulder 26 and the flange 28of the head. When thus assembled the fitting 23 and head flange 28together with the liner lip are permanently assembled, the fitting 23and head flange 28 together with the liner lip are permanently anchoredby means of an outside weld 35.

By reasonfof theimproved assembly for mounting thetap fitting 23 in thehead of a barrel having a stainless steel liner, the outer end of tapstub 24 is beneath the highest portion of the head '12 and thislhighportion of the head is, in turn, back ofor beneath the plane ofchime flange l9. Thus the head and the stainless steel tap fitting areeifectively protected by the chime when the barrel is up-ended andstanding in an upright position on a chime, and damage to the fittingand the thin liner at the head of the barrel is pre vented. Also it willbe apparent that the out side weld 35 which unites the fitting to thebarrel head is protected against damage and, in the event a leak occurs,it will immediately be observed a'nd may be readily repaired merely byrenewing the weld 35 without removing the fitting.

The improved arrangement disclosed herein eliminates the objectionablepockets hereinbefore mentioned, and it eifects a substantial reductionin the costof manufacture. Furthermore, a continuous smooth interiorsurface is presented hr s t s rfi e a i-t e arrel inerior. Any smalloifset regions which may appear in the drawings arefvery shallow and areapproximately no greater than the thicknessof the metal from which theshell is fabricated. During the fabrication ofth'e barrel the linersections are preformed to the inner'contonr of the shells, arewelded'tog'ether, and then the shell sections, with the chimes and hoopswelded in place, are fitted around th' 'e'corn plete linerin closecontact thereto. Thereafter, the shell sections are waded together in te ma iner he ein e o e i ed All this is done without injury to the thinstainless steel ic fihe i e s ma While the invention has been disclosedin a typical or preferred embodiment thereof, it will beapparentto-persons skilled in the art, after understanding the invention, thatchanges or modifications :thereof may be made without departing "fromthe spirit'of the invention. It is aimed in 'the'a'ppended'claims tocover all such changes or modifications.
